the writer, together with Mr. B. E. Walker, F.G.S., of Toronto, Mr. 

 N. J. Giroux, C.E., Mr. J. C. Reichenbach, and others visited this 

 island, where extensive excavations made by the civic authorities had 

 brought to view the fossiliferous strata of the middle Utica. Large 

 blocks of black bituminous shale were examined and a perfect harvest 

 of interesting forms obtained. 



Slabs covered with the remains of graptolites of the genus Lepto- 

 graptus, beautifully presewed and showing the hydrothecse and other 

 points of structure wonderfully well ; colonies ot the sponges recently 

 described for the writer by Dr. Hinde as Stephanella saricta, together 

 with remarkably well-preserve 1 specimens of TriartJirus spinosus were 

 found in tolerable abundance. 



A complete list of the species collected on Porter's Island will be 

 published in a future number of the Naturalist, if desired.

On one occasion, in two hour's search the writer and two friends 

 secured no less than 30 heads of crinoids besides a large number of 

 beautilul examples of Trematis Ottawaensis, Billings and an undescribed 

 bryozoaiy. 



3. Besserers. Ottawa River. 9 miles below Ottawa City. In 

 company with Mr. Lambe of the Geological Survey the writer spent a 

 day collecting in the Post Pliocene marine clays of this locality during 

 low water in September. Besides some fifty specimens of fossil fishes 

 Malloius villosus. Cuvier, collected on this occasion there were 

 obtained remains of shells and plants in tolerable abundance. Some 

 fifty specimens ot plants were sent to Sir William Dawson and include 

 remains of algae or seaweeds, mosses, equisetaceiv, fruits, grasses, sedges 

 and leaves of trees and flowering plants. 



Two fossil feathers were also collected. The first specimen of a 

 fossil feather from those marine clays discovered as far as we know 

 was that obtained by the Marquis of Lome at Green's Creek, during his
